WATER- FILTER.

SPEGIFIGATION forming part of Letters Patent No. 602,823, dated April 26, 1898.

Application filed July 14, 18 9 '7.

To all whom it may concern.-

Be it known that we, FRED BUCK and THEO- DORE Huss, citizens of the United States, residing at Saginaw, in the county of Saginaw and State of Michigan, have invented certain new and useful Water-Filters; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

Our invention relates to water-filters, and especially to that class in which a filteringstone is used; and it consists in the peculiar construction, arrangement, and combination of the various parts, whereby better results are obtained and the device made more durable and better adapted for use.

Figure l is a sectional view of upper end of the filter and coupling. Fig. 2 is a section of the lower end of the filtering-stone and attached parts. Fig. 3 is an elevation of the filtering-stone provided with a metal cap.

In the drawings, 1 is the filtering-stone,which has secured thereto at its lower or discharge end the metal cap 2, fitting over the end of the stone and provided with a central threaded opening 3, in line with the discharge-opening of the stone. This opening 3 receives the threaded end of the discharge or drip piece 4, which also acts as a nut, being provided with a flange 5, adapted to receive a wrench to hold the casing-cap 6 of the casing 7 in position. The inner surface of the casing-cap 6 may fit closely against the base of the metal cap 2 on the stone. A rubber washer 6, as shown, maybe placed between them to make the connection water-tight. It will be seen that the flange of the casing-cap 6 is threaded to engage the casing '7, a washer Sbeing used in this connection to make the joint watertight. The upper end of the casing is provided with a central externallythreaded bored lug 9, and by means of this and the coupling hereinafter described the device is secured to the intakepipe or faucet.

10 is the coupling, and consists of a short tube provided with an ofiset, whereby one end is made smaller than the other. The smaller end is adapted to engage the threaded lug 9 Serial No, 644,509. (N model.)

and pass thereon up to the offset, the faucet or intake-pipe passing into the larger end and against the washer 11, in which position it is secured by means of the set-screws12, which pass through the coupling into the larger end and against the intake-pipe. It will be observed that by having the outer end of the coupling large the coupling is adapted to engage a large or small pipe or faucet, for if smaller than the end of the coupling the setscrews -12 may be passed farther into the coupling, so as to engage the smaller pipe. When the coupling is placed on the intakepipe, the filter is then screwed into the other end and against the washer, thereby making a water-tight connection. It willbe observed that by this arrangement of filtering-stone, metal cap and casing, and the drip-piece the filtering-stone can be 16lTlO\6d,lVll6Il required, by unscrewing the drip-piece and cap of casing, and another stone provided with a metal cap inserted in its place and the parts again placed in position.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A water -filter of the class described, comprising a filtering-stone, a metal cap secured on the discharge end of the stone and having a central threaded orifice, a cap for the casing inclosing the stone provided with a central orifice in line with the orifice of the metal cap of the stone, a drip-pieceadapted to pass through the orifice of the casing-cap and engage the threaded orifice of the metal cap, a lug on the drip-piece adapted to press against the outside of the casing-cap and when the drip-piece is screwed in make a water-tight connection between the metal cap and the casing-cap, as described.

2. In a water-filter of the class described, the combination with a filtering-stone provided with a metal cap, as described, the easing-cap, and the drip-piece adapted to secure the casing-cap and the metal cap of the stone in water-tight connection, of the casing for the stone adapted to engage the casing-cap, means for making their connection watertight, the casing provided with a central threaded bored lug upon its upper end, a coupling having one end adapted to engage the lug, the other end adapted to receive any size pipe smaller than the coupling, and means in the coupling for securing the coupling to a large or small pipe as specified.

3. In a water-filter of the class described, the coupling for securing the filter to the intake-pipe, comprising a tube adapted at one end to receive and engage the filter, the other end adapted to receive the intake-pipe of any size smaller than the coupling, a washer between the ends of the filter and intake-pipe, and means, such as set-screws, for securing I the intake-pipe within the coupling, and means, such as turning the end of the filter into the coupling and against the washer for making a water-tight connection, as specified.
